Description

Technical Field

[0001] The utility model belongs to the technical field of chains, and in particular relates to a quick-release transmission chain. Background Art

[0002] Chains are generally metal links or rings, and are mostly used for mechanical transmission and traction. They are chain-shaped objects used to block traffic channels. Chains used for mechanical transmission. Existing chains are usually composed of chain plates, chain pins and bushings.

[0003] At present, when a user needs to disassemble a chain, the entire chain usually needs to be removed to disconnect the chain, which is troublesome to operate and is easy to damage the chain parts, resulting in the chain as a whole being unable to be put into use again. The disassembled chain is then reconnected, which is easy to reduce the stability of the chain, resulting in not only high maintenance costs but also affected stability during use of the chain. Utility Model Content

[0004] The technical problem to be solved by the utility model is that it is difficult to achieve a balance between rapid quick release and connection stability in the existing chain.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a quick-release transmission chain, including an outer link plate, a transition link mechanism is movably installed on the left side of the outer link plate, the transition link mechanism includes a transition chain plate, a transition O-type pin, a through hole and a transition cotter pin, the transition chain plate is movably installed on the left side of the outer link plate, the transition O-type pin is movably installed in the inner cavity of the transition chain plate, the through hole is opened at one end of the transition O-type pin, and the transition cotter pin is movably installed in the inner cavity of the through hole.

[0006] As a preferred embodiment of the utility model, a connecting pin is fixedly installed on the front side of the outer link plate, and an inner link plate is movably installed in the middle part of the two outer link plates.

[0007] As a preferred embodiment of the present invention, a roller is fixedly mounted in the middle portion of the two inner link plates, and a sleeve is fixedly mounted in the inner cavity of the roller.

[0008] As a preferred embodiment of the present invention, the two outer link plates are installed in parallel and equidistantly.

[0009] As a preferred embodiment of the present invention, the two inner link plates are installed in parallel and equidistantly.

[0010] As a preferred embodiment of the present invention, the inner diameter of the roller is greater than the outer diameter of the sleeve.

[0011] As a preferred embodiment of the present invention, the inner diameter of the sleeve is larger than the outer diameter of the connecting pin.

[0012] The beneficial effects of the utility model are:

[0013] 1. A quick-release transmission chain, by installing a transition link mechanism in the chain, when the chain needs to be disassembled, only the transition link mechanism needs to be removed, without completely dismantling the entire chain, making it easier and more convenient to disassemble the chain. The chain can be separated by simply unfastening the transition chain plate in the transition link mechanism, and the stability of the chain is not easily reduced when the chain is subsequently reconnected. When two chains of different specifications need to be connected in the transmission system, the transition link mechanism can also act as a connector, which enables chains of different specifications to be tightly connected together to ensure the continuity and stability of the transmission.

[0014] 2. This quick-release transmission chain, through the setting of the connecting pin shaft, facilitates the fixing of adjacent chain links together, so that it can rotate smoothly and transmit power. Through the setting of the sleeve, the friction and wear between the chain and the connecting parts can be reduced, and additional support and protection can be provided. Through the setting of the roller, the friction between the chain and the transmission gear or sprocket can be reduced, so that the chain can roll smoothly. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] like Figures 1 to 4As shown, the utility model provides a quick-release transmission chain, including an outer link plate 1, a transition link mechanism 2 is movably installed on the left side of the outer link plate 1, the transition link mechanism 2 includes a transition chain plate 201, a transition O-type pin 202, a through hole 203 and a transition cotter pin 204, the transition chain plate 201 is movably installed on the left side of the outer link plate 1, the transition O-type pin 202 is movably installed in the inner cavity of the transition chain plate 201, the through hole 203 is opened at one end of the transition O-type pin 202, and the transition cotter pin 204 is movably installed in the inner cavity of the through hole 203.

[0022] refer to Figure 1 , Figure 3 and Figure 4 A connecting pin 3 is fixedly installed on the front of the outer link plate 1, an inner link plate 4 is movably installed in the middle of the two outer link plates 1, a roller 5 is fixedly installed in the middle of the two inner link plates 4, and a sleeve 6 is fixedly installed in the inner cavity of the roller 5.

[0023] The above solution is adopted: by setting the connecting pin 3, it is convenient to fix adjacent chain links together so that they can rotate smoothly and transmit power.

[0024] refer to Figure 1 , Figure 3 and Figure 4 The two outer link plates 1 are installed in parallel and equidistantly, the two inner link plates 4 are installed in parallel and equidistantly, the inner diameter of the roller 5 is larger than the outer diameter of the sleeve 6, and the inner diameter of the sleeve 6 is larger than the outer diameter of the connecting pin 3.

[0025] By adopting the above scheme: through the setting of the sleeve 6, the friction and wear between the chain and the connecting member can be reduced, and additional support and protection can be provided. Through the setting of the roller 5, the friction between the chain and the transmission gear or sprocket can be reduced, so that the chain can roll smoothly.

[0026] Working principle:

[0027] When in use, it is first necessary to determine the position of the transition link mechanism 2, that is, at which part of the chain it is installed. Usually, the transition link mechanism 2 will be located at the position where the chain needs to be disassembled. When the chain needs to be disassembled, find the position where the transition link mechanism 2 is installed, and loosen the transition O-pin 202 on the transition link mechanism 2 to separate the transition link mechanism from the outer link plate 1 of the adjacent chain link. Once the transition link mechanism 2 is separated from the adjacent chain link, the chain can be divided into smaller parts, which can reduce the length of the entire chain and make the disassembly process more convenient and quick. After the chain is disassembled, necessary maintenance, cleaning, lubrication or replacement of damaged parts can be carried out. After completing the maintenance or replacement work, the chain can be reassembled through the transition connection mechanism 2 in the correct order and method, and ensure that all connecting parts are firmly fixed.

[0028] To sum up: this quick-release transmission chain, through the coordinated use of the transition chain plate 201 and the transition O-pin 202, solves the problem that when the user needs to disassemble the chain, the entire chain usually needs to be dismantled to disconnect the chain, which is troublesome to operate and can easily damage the chain parts, resulting in the chain as a whole being unable to be put into use again. The disassembled chain is then reconnected, which can easily reduce the stability of the chain, resulting in not only high maintenance costs but also affected stability in use during the use of the chain.
